[1] | Net interest income is the difference between interest earned on assets and the cost of liabilities to fund those assets. Interest earned includes actual interest earned on segment assets and, if the segment has excess liabilities, interest credits for providing funding to the other segment. The cost of liabilities includes interest expense on segment liabilities and, if the segment does not have enough liabilities to fund its assets, a funding charge based on the cost of assigned liabilities to fund segment assets.
[2] | Noninterest income includes activity from certain residential mortgage loans that were initially originated for sale and measured at fair value, and subsequently transferred to loans held for investment. Gains and losses from changes in fair value for these loans are reported in earnings as a component of noninterest income. For the three and six months ended June 30, 2024, the Company recorded a net increase in fair value of $184,000 and $186,000, and a net decrease in fair value of $520,000 and net increase in fair value of $57,000 for the three and six months ended June 30, 2023, respectively. As of June 30, 2024 and 2023, there was $13.9 million and $14.3 million, respectively, in residential mortgage loans recorded at fair value as they were previously transferred from loans held for sale to loans held for investment.
[3] | Noninterest expense includes allocated overhead expense from general corporate activities. Allocation is determined based on a combination of segment assets and FTEs. For the three and six months ended June 30, 2024, the Home Lending segment included allocated overhead expenses of $1.5 million and $3.0 million, compared to the three and six months ended June 30, 2023, of $1.6 million and $3.2 million, respectively.
